useful improvements 'in gas stoves and hasn l particular reference to improved burner constructions for vgas stoves, the present application being a' division lof my copending application Serial Number 511,283 filed October 29, 1921 upon gas stoves.

The primary object of the invention is to provide an improved burner construction for gas stoves whereby the same may be conveniently manufactured in considerable, quantity at a minimum expense with vthe result-antproduct extremely eicient and durable.

With the above general object in view and others that will appear as the ,nature ofv the invention is better understood, the invention consists 1n the novel form, combination and arrangement of parts heremafter more fully described in connection with they accompanying drawing, in which like characters of reference 'indicate similar parts throughout the views.

In the drawing, Figure 1 is a top plan view of the burner, and Figure 2 is a central transverse sectional with the present invention.

The burner includes a hollow cast body as clearly shown in Figure 1 including a plurality of radial burner members 21 arranged in spaced relation and connected by integral outwardly inclined webs 22, the body being preferably open at the center so as to provide a cylindrical inner wall`23 which also connects the burnermembers 21,

' the webs 22 being extended-at an outward inclination for the purpose of draining grease or the like as will be apparent from an inspection of Figurel. The bottom edges of the side walls of the burner members 21 join with the edges of the webs 22,v and being similarly inclined, provide comparatively large clearance between the .bottom'wall 24 and the webs 22 for the instantaneous passage of the gas to all of the burner members 21 from the-inlet 19 with al minimum obview of a burner constructed in accordancel struction, which clearancegradually inf creases from the outer wall of the burner to .PATIENTOFFICE-:g*

the inner wall thereof. The burner members 21 are provided with lV-shapedroof or topv wall portions which merge -with slightly inclinedfnearly vertical side walls, the lower edges of 'which connectwiththe webs 22 and Y by reason vof this particular formation of the Vburner 'members practical drainage thereof isinsured while the liability of the'fy burnenholes25 vbecoming clogged is reduced to a minimum, said burner holes being'provided in considerable quantity l through the; i

top walls of the burner members. v t v The body of the burner is preferably cast with the bottom open and with the lowerv margins of the inner and outer walls thereof set at an inclination vas clearlyseen'in lig-` ure 1 so that when the botton wall 24 has its lnner and outer margins flanged over on the lower margins of said walls as at 26, said bottom-Wall is effectively held 'to thebody portion and with gas-tight joints so that leakage of the gas between the body Vand bottom members will not occur. In this way,

the bodyportion may be cast withoutfthef` usual coring operation and the'bottom member 24: may be constructed of sheet metal of the desired gage, stamped in disk rform with a central opening.

. It is believed that the construction and advantages of the presenty invention will be readily understood and appreciated by those skilled in the art from 1 the foregoing description.

Minor changes may be madewithout de v parting from the spirit and scope of the invention as claime What is claimed as new is f Y 1. A two-piece gas burner including a cast upper section emboding radial burnermembers having a common inletv and providedy with a plurality of burner perforations, said cast upper section havingfan open bottom and a central opening, and a closingor bottom plate for-the bottom vof said cast sectionk including a disk of sheet metal provided with a central opening and'having its inner and outer margins anged over the lower margins of the inner and 'outer walls of said cast sect1on.

2. A two-piece gas burner including a cast upper sectionembodying radial burner meml bers `having' a` common 'inlet andv provided with a pluralityjof burner perforations,

said cast upper section having an open bottom anda Centralopening, and a closing or bottom pla-te for the bottom of said cast section including a disk of sheet metal provided with a central opening andhaving its inner and outer margins flanged over the lower margins of the inner and outer walls ofsaid cast section, the radial burner members having sidewalls, Vthe lower edges of which gradually inc-line outwardly, and outwardly inclined webs having their edges oonnecting with lower edges of said sidewalls of the burner members.

A two-piece gas burner including a cast upper section embodying radial burner menibers having a commonV inlet and provided with a plurality of burner perforationsl, said cast upper section having an open bottom and a central opening, and av closing or "bottom plate for the Ybottom of said cast section including a disk Iof sheet metal provided with a central opening and hav'ipg itsl inner and outer margins Vflanged over the lower margins of'the `:inner and outerwalls of said cast section, the radial burner members having side walls7 the lower edges of which gradually incline outwardly, and outwardly inclined webs having their edges connecting with lower edges of said side walls of the burner members, said burner members having substantially V-shaped top w'allsf 4. A gas burner including a cast upper section having radial burner members connected by outwardly inclined webs and provided'with inner and outer walls, the inner wall defining a eentral opening in the upper section, and v a ysheetfme'tal dis-k having a. centra-l opening with its vinner and outer margins flanged over the inner and outer 'walls of said upper section into gas-tight Contact therewith.
